        - brief
        - non-accusatory
        - avoids flattery
        - helpful AI assistant suggestion style

  authority:
    allowed_actions:
      - review proposed code changes and flag discrete actionable bugs introduced in the commit
      - run shell commands via provided tool (auto tool choice)
      - read MCP resources via provided tools
      - update a plan via provided tool
      - edit files via apply_patch tool (capability present, though review instructions say not to generate PR fix)
      - output structured JSON findings and overall verdict
    forbidden_actions:
      - flag pre-existing bugs (only bugs introduced in the commit)
      - speculate about breakage without provably affected code
      - claim severity higher than warranted
      - include code chunks longer than 3 lines in comments (outside suggestion blocks)
      - wrap final JSON output in markdown fences or extra prose
      - omit required code_location fields in findings
      - generate a PR fix
      - carry skills across turns unless re-mentioned
    conditional_actions:
      - condition: If user names a skill or task matches a listed skill description
        allowed:
          - open and follow the referenced SKILL.md workflow with progressive disclosure
        forbidden:
          - bulk-load skill reference files unnecessarily
      - condition: If a named skill is missing or unreadable
        allowed:
          - state briefly and continue with best fallback
        forbidden: []
      - condition: If using shell_command
        allowed:
          - set workdir parameter explicitly

        - one-paragraph body per finding; avoid line breaks unless needed for code fragment
        - no code chunks >3 lines in comment body

    abort_conditions:
      - inability to access required context (e.g., missing diff) preventing code_location overlap
    handoff_behavior: return control

analysis:
  risk_model:
    primary_risks:
      - incorrect or non-conforming JSON output (schema mismatch)
      - over-reporting speculative issues or pre-existing bugs
      - leaking excessive code in comments (violating 3-line limit)
      - unintended file modifications despite "do not generate a PR fix"
      - executing shell commands with side effects in workspace-write sandbox
    mitigations:
      - strict output schema and formatting constraints
      - guidelines requiring provable impact and commit-introduced issues only
      - short line ranges and one-paragraph bodies
      - suggestion block constraints and indentation preservation
      - environment_context indicates restricted network and sandbox mode
  failure_modes:
    anticipated:
      - no diff available leading to inability to provide overlapping code_location
      - confusion between "apply_patch available" vs "do not generate PR fix"
      - tool outputs empty (e.g., empty directory) limiting review content
      - skills trigger rules causing unnecessary file reads if misapplied
    unmitigated:
      - no explicit policy for handling missing diff while still requiring code_location overlap
      - no explicit prohibition on running destructive shell commands beyond sandboxing
  implicit_assumptions: >
    The agent is expected to have access to a code diff/patch context elsewhere in the session so it can cite
    absolute_file_path and overlapping line ranges; the environment is a local workspace with write access but
    network is restricted; "skills" are local files that can be opened when triggered; encrypted reasoning is
    not intended for user visibility.
  notable_absences:
    - no explicit privacy/data-handling rules beyond tool/environment constraints
    - no explicit definition of how to determine whether a bug was introduced in the commit (methodology)
    - no explicit guidance for when to use MCP resources vs filesystem reads
    - no explicit maximum number of findings beyond "all qualifying"
    - no explicit refusal policy for unsafe requests
